GLASS-FEEDING APPARATUS.

Application filed September 25, 1926.

The present invention relates to improvements in glass feeders, andparticularly to means for steadying and guiding mold charges duringtheir formation and after theirseverancc from the main body of glass. Itis customary to mount charge guiding means directl upon the shearingmechanisn but with such an arrangement it has been found that thecharges are displaced laterally or tilted so that they are not properlydelivered into the molds. The above condition is due to the fact thatthe guiding means being attached to one of the shear arms, moveslaterally during the formation of and after severance of a charge.

An object of the present invention is to provide a mold charge guideadapted for nmlti-directional adjustment and mounted independently ofthe'shear mechanism and adapted to remain stationary in a positionadjacent to the mold charges being formed and severed for minimizinglateral movement of the mold charges under influence of action of theshear mechanism.

Another object is to provide charge guid- 'ing means adjustablehorizontally toward and away from and longitudinally of the feeding axisof the feeding mechanism.

A further object is to provide a charge guiding and steadying devicemounted independently of the shear mechanism and ca pable ofnmlti-directional adjustment during operation of the feeding mechanismand other apparatus associated therewith.

Other objects will be apparent hereinafter.

In the accompanying drawings:

Fig. 2 is a top plan view of the charge guiding means, the glass feederand cutters being shown in dash and dot lines.

Fig. l is a section taken on the line IVIV of Fig. 2.

In the accompanying drawings, the charge guiding means is illustrated inconnection with a feeder boot adapted to contain molten glass from whichmold charges are formed, such charges being periodically severed from astream issuing through the lmttom outlet opening 9 by shear mechanismincluding a pair of opposed cutters 11 mount- Serial No. 137,774.

ed upon arms 12 below the boot or forehearth. T 1e charges are deliveredto molds M through. their open upper ends. A plunger 8 regulates theissue of the glass.

A hanger or bracket 13 is formed with a vertical attaching arm llthrough which bolts or the like fasteners 15 are passed for rigidlyattaching the hanger to one side wall of the feeder boot 10 (see Figs. 1and A horizontal extension 16 arranged at right angles to the arm 14 isformed. with a vertical bolt opening near its outer end. This hanger 13is provided at the side opposite the entension 16 with relatively rightangularly disposed bearings 1? having threaded openings adapted toreceive adjusting screws 18. These adjusting screws are controlled byhand wheels 19 and cooperate with associated mechanism to change thelocation of charge guiding means carried by an arm 21, as will behereinafter brought out. The adjustments may be made while the feeder isin operation. The inner adjacent ends of the two adjusting screws 18abut right angularly disposed vertical sides of the head 20 formed onone end of-the charge guide carrying arm 21, which is fulcrumed to theouter end of the aforementioned. extension or arm 16 of the hanger 13.Such attachment of the charge guide carrying arm to the extension 16 iseffected by means of a pivot bolt 22 extending through a verticallongitudinal slot 23 in said arm and through the bolt hole in theextension 16. This connection provides for both pivotal and slidingmovement of the charge guide carrying arm with respect to the hanger 13.The arm 21 is formed with a depending re-enforcing web 24, one end ofwhich terminates below the head-20 and is formed with. an eye 25 towhich one end of a coil spring 26 is attached. The other end of the coilspring is fixed to a tensioning device, including a screw 27, extendingthrough a bearing 28 and adapted to be ad justed longitudinally thereinby means of a nut 29.: This bearing 28 is located between the adjustingscrews 18 and is integrally cast with a depending flange 4-5 on anextension 30. The hanger, including the attaching arm 14, extensions 16and 80, and the several bearings is preferably formed in a singlecasting and. includes suitable reenforcing ribs (see Figs. 1 and 2.)

The coil spring 26 yieldably holds the head 20 of the charge guidecarrying arm 21 in paratus.

engagement with the inner ends of the adjusting screws 18 so that withmanipulation of either screw, the relation between said arm and thehanger will be changed and in turn shift the charge guiding meansrelative to the feeding axis of the feeding mechanism.

The forward or inner end of the charge guide carrying arm 2i is providedwith a lateral extension 31. The front edge of the lateral extension 31is provided with a depending flange 32 substantially V-shaped inhorizontal cross section. Adjacent the lower edge of this verticalflange 32 is formed a longitudinally rearwardly extending arm 33 below aportion of the extension 31. Vertically aligned openings 34 are formedin the extension 31 and arm 33 to receive a threaded bolt 35 whose upperend is attached to a charge guide or steadying device 36. This chargeguide 36 includes a horizontal portion adapted to overlie the extension31, the forward end of the guide including a depending flange 37 whoseshape conforms to that of the aforementioned flange 32 at the forwardend of the charge guide carrying arm 21. Opposed guiding ribs 38 areformed upon the charge guide 36 and are slidable in vertical ways 39(see Figs. 3 and 4;). A regulating wheel &0 is arranged between theextension 31 and the arm 33 and is threaded upon the bolt 35 for varyingthe elevation of the charge guide 36 as may be required when theshearing mechanism is adjusted relative to the feeding mechanism.

By adjusting the screw 18 which abuts the outer end of the head 20, thecharge guide carrying arm 21 will be moved longitudinal- 1y, suchmovement being permitted due to the bolt and slot connection betweensaid arm and the extension 16 of thehanger 13. The other adjusting screwbeing stationary, coacts with the spring 26 in preventing lateralmovement of the arm. Thus, it is seen that this longitudinal adjustmentmay be effected 'entirelyindependent of any other adjustment.

In the same manner, the other adjustingscrew 18 may be operated to movethe charge guide carrying arm around its pivot, and during thisadjustment the first screw and the coil spring 26 coact with each otherto prevent longitudinal movement of said arm. 'By alternately operatingthese two screws, the charge guide may be accurately adjusted duringoperation of the feeding mechanism and associated ap- In the event theelevation of the shears is changed, or if for other reasons, raising orlowering of the charge guide 36 is required, such adjustment can beeffected by operation of the hand wheel 40.

Manifestly, certain changes may be resorted to within the spirit andscope of the appended. claims.
